The closest I could find on the Colt web-site was a SS Gov't 1991a1, that has the model # of 01091.

I think it is some sort of a commemorative model built on a Colt by a third party.

I am not sure, but I would make a guess that the 01091Z is simply a 01091 labeled as CA-approved.

Just a guess, but my Defender is a model 07000DZ, it is a Colt Custom Defender. The box is marked accordingly. The regular production Defenders are model 07000D. Maybe the Z denotes Custom of some type???

I think my guess was correct. I just checked the box label on my NIB 01991Z, it is marked Custom 1991A1. Mine is matte blue, the one you are referring to model 01091Z is probably the same thing but in matte stainless. These are the Lew Horton guns, I can't remember what is custom about them except they came with a Videki trigger, may have some other features though..They have the billboard 1991 rollmarks..hope this helps..

In a recent gun periodical there was a full-page ad for a Colt 1911, it was gold engraved, and really sort of "pimped-out". It was some kind of commemorative. A new model Colt.

It was for sale, and they did NOT say "not for sale in CA" or any hint of any disclaimer like that. Not even "may not be for sale in all areas." There was NOTHING to indicate I couldn't buy it.

I assumed that was the one.

It may have been American Rifleman, or it might be Guns&Ammo, I don't think it was Front Sight. But it's in the last couple months.

Did you try a Google search?

I see Gun Broker Has one of these .....

anybody know anything about these?

 

[dakota1911]

I would go with dsk on this one as a best guess.

That's old model for a distributor, no longer offered. You can only look for used.

"Z" suffix can denote any change in any model.

Looks like in this case the Z denotes Hogue wrap arounds.

 

[BLikeYork]

it also has a different hammer .... seems to be some kind of Lou Horton model maybe ....

are these made by Colt then altered by a third party by any chance?

 

[Call 1-9-1-1]

Speaking of Z marks, anyone know what the "Z" stamp on this 1911 means?
I bought it (a 1996 Government Enhanced model) recently and noticed the Z
mark on the frame.

Guys, a model O1091Z means a custom factory model O1091.

Colt uses the letter "Z" to name custom editions or Custom Shop guns.

Most of my Colts were made on a custom basis by the Custom Shop, all of them showing model numbers ending with a "Z"

Hope it helps,
